Catalyst Volume 20 Issue 2
This issue of Catalyst includes the following articles:
Zeolites are naturally occurring sponge-like materials which can be used as chemical sieves and catalysts.
This article introduces Dorothy Hodgkin and her work as an X-ray crystallographer.
Using zebrafish as a model for human disease in scientific research is the main subject of this article.
This article focuses on how Robert Hooke published his results on the law of springs.
The article looks at the building of molecular 'traps' to mimic the surface of a cell.
This article describes a film giving a variety of reasons for studying science.
The article presents the arguments for and against fluoridation of water supplies.
This article looks at experimenting with fluoride toothpaste on eggshells (as a substitute for teeth).
The Nobel prize for physics 2009 rewards scientists who developed optical fibre systems and CCDs.
A Catalyst article about Dorothy Hodgkin who was a pioneering scientist, a peace activist, a mother of three and a Nobel Prize winner. The article looks at her life and work in science. She did valuable work as an X-ray crystallographer and in finding the structure of biologically important molecules such as...
This Catalyst article describes how fish can help scientists to learn more about human biology. Understanding how human bodies work and what causes human disease is the key to future medical breakthroughs. Most discoveries in medical science are a result of experiments that cannot be performed on humans. Animal...
This Catalyst article looks at the work of Robert Hooke, an employee of the Royal Society, Britain's oldest scientific society. His job was to present two or three different experiments each week to the assembled members of the society – and this was at a time when experimentation was new and there were no books of...
This Catalyst article explains how chemists build molecular 'traps' to mimic the surface of a cell. To scientists, sugar is much more than a food; sugar molecules can also form polymers which act as ‘molecular bar codes’ to help cells recognise each other. The article describes how chemists made a synthetic...
